IMPROVED TIRE-UPSETTING MACHINE.

The Schedule referred to in these Letters Patent and making part of thesame To all whom @t may con-cern.'

.Be it known that I, THOMAS SULLIVAN, of Gorning, in the county of Steuben and State of New York, have invented certain new and useful Improveaccompanying drawings and to the letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement ot' a tire-upsetting machine, as will b e hereinafter fully set forth.

In order to enable others skilled in the art to which my invention appel-taies tomake and luse the salue, l will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure l is a side view,

Figure 2 is a longitudinal vertical section, and

Figure 3 is an end view of my machine.

A represents a cast-iron frame, of suitable dimensions, having a lixed bed-plate, B, and a movable bedplate, C.

In the frame A, at the end of the fixed bed-plate B, and also at the outer end of the movable bed-plate O, archooks F F, for retaining eccentrics D D, which work therein by means of their handles E E, and serve to hold fast the tire, about to be shortened, to the bed-plates.

N is a lever, applied to the pinion M, which acts upon a curved rack. I, connected by the arm G to the movable bed-plate C, and draws yit toward the fixed bed-plate B, thus shortening the tire at the point which had been heated.

Under the movable bed-plate C is a friction-roller, H, to give ease of motion.

. The curved rack I is hinged to the arm G and to the frame by means of the hinges J K, as seen in fiv. 2. Y

z:On one side of the stationary bed-plate Bis an upward-projecting flange, with groove O, for the insertion of a lever to keep thetire down, if required.

The whole machine is to be placed upon an ordinary anvil, with a pin, L, projecting from its under side, inserted in the hole in the anvil.

'Having thus fully described my invention,

-What I claim as new, and desire to secure by Let ters Patent, is- Y 1. In combination with the movable bed-plate C, arm G, and curved rack I, the pinion M, lever N, and friction-roller H, all constructed Aand operating substantially as and for the purposes herein set forth.

2. The combination and arrangement of the frame A with p in L, bed-plates B C, eccentrics D D, rack I, and pinion M, all constructed and arranged to operate substantially as and for the purposes herein set forth.

3. In combination with the fixedv bed-plate B, the grooved flange O, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own,

I afiix my signature in presence of two witnesses.
